I just got my bike back on Feb 6th from having the ECM upgrade. It lasted 300 miles and required a Tow Buster call to deliver it to the Honda Shop. Stopped for gas and the bike had no power. When it got to the Honda Shop it would not start at all; however, when they put another new ECM in, it worked just fine. The original ECM had ~ 49,000 mile on it. Hind sight is 20/20. I would probably have been better off putting up with the over heating instead of this. To make matters worse, the towing company cracked my front fender while loading the bike. They are going to replace it.
